Solar photovoltaic (PV) panels and the vegetation under them consist of a combined system that could provide not only clean electrical power but also an effective preventive measure against wind erosion in sandy ecosystems. Here, by evaluating the effectiveness of the two-tier model, this study focused on the socioeconomic and environmental co-benefits of the solar PV industry in sandy ecosystems. The results showed that the ecosystem services provided by the combined system land were 24 times higher than those provide by natural recovering land. The combined system could achieve $5258.86 × 10⁴ in benefits per year, including $3897.48 × 10⁴ from electricity and $1361.38 × 10⁴ from ecosystem services value. The ecosystem services value could reach 34.93% of the electricity benefits value and become a vital part of the total valuation. The results indicated that electricity benefits and considerable ecosystem value could be generated from the combined systems. These combined systems have great potential for combating desertification and should be considered appropriate public investment projects with high economic and social rates of return in arid areas.

太阳能光伏（PV）面板及其下面的植被由一个组合系统组成，该系统不仅可以提供清洁的电力，而且可以有效地防止沙质生态系统中的风蚀。在这里，通过评估两层模型的有效性，本研究集中于沙质生态系统中太阳能光伏产业的社会经济和环境共同效益。结果表明，合并系统土地提供的生态系统服务比自然恢复土地提供的生态系统服务高24倍。合并后的系统每年可实现5258.86美元×10 ⁴的收益，包括3897.48美元×10 ⁴的电力收益和1361.38×10 ⁴美元的收益。生态系统服务价值。生态系统服务价值可能达到电力收益价值的34.93％，并成为总估值的重要组成部分。结果表明，组合系统可以产生电力收益和可观的生态价值。这些综合系统具有防治荒漠化的巨大潜力，应被视为在干旱地区具有高经济和社会收益率的适当的公共投资项目。
